I have a custom site template wsp file & workflow wsp file.

I am trying to combine these two wsp file to one.

Is that possible to do this in office 365 with sandbox solution, and if so, how?

  • Are office-365 and wspbuilder tags 100% related?

It is possible, you'll have to replicate steps that Visual Studio automagically do for you ).

  1. Extract wsps. Because .wsp is .cab archive, you'll need a tool to deal with cabs. I used Total Commander plugin for the purpose. Extract into separate folders.
  2. Merge content of manifest.xml from those folders into one manifest.xml
  3. Merge files from those folders (copy/move)
  4. Archive this merged folder into .cab file using tool
  5. Rename .cab to .wsp

That is pretty easy unless you have files with the same name in both archives

  • If you need to do it regulary and you are developing those solutions, there are another option using Visual Studio to create a single (Installer) SharePoint project

  • i'm confuse about how to Merge content of manifest.xml, because mainfest.xml contains <Solution SolutionId=""> and mainfest.xml contains only one Solution element Sep 8, 2015 at 9:35
  • Each wsp corresponds to solution. You have to decide, either you want new solution that includes both wsps or you want to upgrade one of the wsp with the other. I later case, you can keep the SolutionId
